Default Handler

The utility provides a macOS‑only tool for modifying which application handles a given URL scheme. By allowing users to assign or reassign the default handler for protocols such as http, mailto, or custom schemes, it gives direct control over how links and protocol requests are processed on the system. The program operates at the system level, updating the appropriate macOS settings so that the chosen application is invoked whenever the associated scheme is encountered.

It is intended for macOS users who need to adjust their workflow, troubleshoot conflicts between multiple applications that claim the same scheme, or customize the behavior of specific protocols without manual editing of configuration files. The tool presents a straightforward interface for selecting the preferred handler and applying the change, simplifying what would otherwise be a series of command‑line or preference‑pane steps.

The software is marked as stable and is distributed as a core utility for macOS, indicating that it has reached a mature state suitable for everyday use. Its focus on URL scheme handling makes it a niche but useful addition to a macOS power user’s toolkit.
